Hey Pedro, I don't have any first hand experience of La Decouverte but I'll get the ball rolling. We have some friends whose kids went there and they had a generally positive experience. It is 50/50 Eng French, so I think your plan sounds good to use it as a stepping stone towards public school. (our kids are in public school and I think its great by the way). One complaint I remember they had about La Decouverte was that there 's not a great outdoor play area for the kids and they don't do a lot of gym activities. It is quite close by the most of the UN organisations if that's a concern for you and concerning the issue of posh schools, I really don't think its by any means the poshest (if its posh at all!). To answer your final question, I would say from my limited experience that it would have a properly international atmosphere there.

Good luck with your move! Any other questions I could answer just get in touch.

My son attended here  - very good school.

Hi,

I've heard many great things about La Découverte from 2-3 colleagues. I was in their waiting list but decided not to move forward with their offer two years ago because I live a bit far from Sécheron. They will open this summer a new campus in Mies that also looks great! We tried for months but were not able to move closeby (pff very difficult to find reasonably priced housing in Mies)...  

We live close to HUG, and currently my daughter attends a school that is very similar to La Découverte - it's called Mosaic and it's in Champel. Small classes, 1 week English, 1 week French. She is now perfectly trilingual (we also speak Spanish at home). We are pretty happy with the school. You could also consider it, depending on the location of your appartment/house. 

Good luck, Alejandra
